Looking at the tempering table from Crucible,
http://www.trugrit.com/CPM154HeatTreatSpecs.pdf
results are pretty similar at tempering temps of 400-900 F, depending on quench.
Can I imply that if I temper at 400, then overheat it while grinding, it won't affect hardness? I doubt I'll be going over 900 during grinding...
After badly warping my last batch (I think I laid them on my anvil to cool some more while they were still hot enough to matter) I'm thinking a grind in the hardened state might be smart, in case of slight warpage.
Thanks,
Andy
